Do not answer Twice
I have a principles that it is called "Do not answer twice"
The idea is that I don't want to answer the same question more than once.
This sounds like a crazy optimization idea, but in my scale it is needed.
After I've founded React community in Brazil, and start answering many questions every day. Then, I realize that most of the questions will repeat themselves once in a while, like a cycle.
I decide to stop answer questions in private, and asking people to ask their questions in public on Twitter and tag me. I did a retweet of their questions, and answered them in public.
So, you someone else asks the same question, I just reuse my answer.
I write answers as tweets, tweet threads, blog posts, articles, and here in my zettelkasten.
